Blocking pain receptors. Researchers recently identified a protein in tooth cells that helps detect cold, possibly opening a path for new treatments for tooth sensitivity. The researchers found that mice without any of the protein in their teeth didn’t sense pain from cold materials in their mouths. The study’s insights suggest that new treatment options could block the cold-sensing protein to eliminate temperature-related sensitivity. Treatments that block the protein could perhaps one day be delivered through chewing gum or through strips that are applied to the teeth directly.

Controlling sensitivity through remineralization. “Remineralization” may sound like something a ray gun would do in a sci-fi movie. But it’s actually a simple process that occurs naturally inside your mouth every day, helping to repair lost enamel and to prevent cavities. The gradual wearing away of tooth enamel can leave the nerves inside the tooth more exposed, so anything that restores enamel is key to helping prevent tooth sensitivity. Researchers are currently seeking ways to give your mouth a boost as it restores lost enamel. The approach uses a painless electric current to drive minerals back into the teeth. One day the process could potentially treat tooth decay and sensitivity in-office without the need for more invasive or painful procedures.
